Electrified repelling and killing device for slugs has broad metal baseplate and centrally positioned wire kept at potential difference of twelve Volts

摘要

The conducting baseplate (3) may be at earth potential and may be 50 mm broad. It may be 5 mm thick and slightly curved, on a radius of 150 mm, so that the top surface is convex as seen in transverse cross-section. The baseplate may be cut to the desired length. There are insulators (1) at intervals along the centerline of the baseplate, holding a bare wire (2) charged at a potential difference of twelve Volts. The centerline of the wire may be at a distance of 5 mm from the baseplate. The 12 Volt current may be provided by a step-down transformer connected to a 220 Volt mains supply.
